Fedora 19 vs. Fedora 20 Linux Benchmarks

Nouveau users may see benefits too, but the performance of the open-source
NVIDIA driver is still severely crippled due to lack of proper re-clocking support.

There are also functionality improvements with the Fedora 20 upgrade like Radeon
DPM (Dynamic Power Management) is an experimental option, new hardware enablement,
etc. If there was Mesa 10.0, Intel Haswell / Ivy Bridge hardware would have also
seen OpenGL 3.3 support.
